'Exhilarating' is one way to describe the feeling you get when climbing the Alpine Tower! Girls will work with their group as they challenge themselves to climb their way to the top. The Alpine Tower is a challenge-by-choice experience, so girls ultimately decide how high they'll go. Individually registered girls must have an adult present. Bring a sack lunch. Adults will not climb during this event. Girls must be at least 10 years old to participate.
